2.2L Duratorq TDCi Diesel Engines
Hi all,
My ST TDCi has started making a whistling noise once the Turbo builds from 1500rpm upwards & gets higher pitched & more intense as the revs climb. It is like a distant police siren raising & lowering "WoooOOOOO oooooooooooooo". I have had a split boost pipe from Inter-cooler to EGR...
